For years, Assassin’s Creed Odyssey has remained a gold standard for action-RPGs set in Ancient Greece. Even after the launch of Valhalla and Mirage, Ubisoft continues to support Odyssey with crucial stability patches. The most significant of these late-stage updates is Assassin’s Creed Odyssey update 1.5.6 download patched—a release that confused many players upon arrival. Was it new content? A next-gen upgrade? A bug fix?
This article unpacks everything about Update 1.5.6: what the “patched” version fixes, how to download it on every platform, file sizes, hidden changes, and troubleshooting common errors.
When you install the fully patched 1.5.6, here is exactly what changes in your game:
File Size: ~1.2 GB (PS4) / ~980 MB (PS5 patch via backward compatibility)
Steps:
Troubleshooting: If you see “Already latest version” but still encounter the lieutenant bug, manually delete your game’s saved profile data (not the save games) from Settings > Storage > Saved Data. Relaunch the game to force a profile rebuild.
The core of the 1.5.6 download focused on squashing persistent insects that had plagued the title.
For players reinstalling the game or updating it after a long hiatus, the download size for Update 1.5.6 varied by platform:
Important Note on "Patched" Files: If you are downloading the game today via platforms like Steam, the Ubisoft Connect app, or console stores, you do not need to manually search for patch files. The version you download is automatically the fully patched v1.5.6 iteration. The "patched" terminology often seen in search results typically refers to the final pre-cracked versions of the game used for preservation or offline play, but for the average user, a standard installation will include all 1.5.6 optimizations.
The headline feature of Update 1.5.6 was the formal cessation of live service content. Ubisoft announced that weekly Olympus Lieutenants and Mercenary Live Events would no longer rotate. However, the patch ensured that all rewards from these events remain accessible to players who might have missed them originally.
Absolutely yes – with one caveat.
If you are a new player or halfway through a fresh playthrough, update 1.5.6 (patched) is essential. It fixes critical memory leaks that cause crashes in the late-game Atlantis DLC. The lieutenant restoration alone saves dozens of hours of recruitment grinding.
However, if you are a modded PC player (using mods like “Greek World Reborn” or reshades), pause updates. The 1.5.6 patch modifies the game’s executable and .forge files, breaking many mods. You can stay on 1.5.3 or 1.5.4 if you prefer mod stability.
For console players, there is zero downside. The patch does not remove any content, nerf builds, or alter microtransactions. It purely stabilizes.
